To mil whom it may concern:-

Be it lgnown that I, HENnY AUG-HIT: acitizen oi' the United States, residing at Emporium, in the county of Cameron, State of Pennsylvania, have invented certain new and useful Improvements in iflasing fleads, of which. the following is a s ecificationQrefer ence being had therein. tofilhe; accompanying drawing.

*The inventioi has for'an ob'ect-to provide a an impr'oved construction} and arrangement of easing headfor oil -brl gaswells comjpriin of the well tubing or casing, said Sectronsbeing securedto'gether by any suitable means with a pack mg between them to prevent the escape of oil or gas, {the u per'pbrtion'of the. casing head being. 'rovi ed wlth. agate orvalve whereby tha ow of liquid or gas from the well may be out offor controlled. Other and further objects'and advantages of'the invention will be hereinafter set forth and the "novel featuresv thereof defined b y the n the drawing :.'-Figure 1 is an elevation showin the manner of applying the same to a well ig. 2 is a similar view showing the invention in position upon a well, and Fig. 3 is a detail section f the 'l-owerpart of the easinghead. a

'Referring to the drawing, the numeral 1 designates the upper end 0 -a well casingor tubing which is passed through a heavy anchor or platform 2 Weighted inany' suitable manner, for instance by stones, as shown in placed around the well casing 01' tubing, 1, each section'being'secured to the anchor 2 by any desired means, for instance, bolts 5 passing through the flanges 4 on the lower ends of the sections and also throu h the anchor, as shown in Fig. 2. Each of the segmental sections. is provided at its abutting edge with for joining the sections-together and in contact with the packing 8 surrounding thewell tube in order to form a perfectly tight joint between the parts. Intermediate of the ends of each section a tee i2 is provided to which Specification of Letters Patent.

the upper end of the well tubing, as shown in F g. 1, and when brought together with an interposed packing 18, they are securely bolted andthe end fla es also secured to the anchor to retain the ead'against lon V tudinal movement relative to the well tu e or casing. The distributing pipes are then connected to the coupling tees in the usual manner and the valve carried by the head maynow be closed to prevent the escape from the. well and cause the samejto flow through the conducting pipes; It will be obvious that a partial closing of .this'v'alve will determine the ressure in these pipes and the flow may a so be regulated by the yalves therein to out it off on either or both sides in caseof fire. From the above it will he seen that the invention is especially adapted for in connection with high pressure wells or those difficult to centre .5 The sections of the head being applied mm o posite sides ofthe discharge of the well 0 not encounter the pressure therefrom and, in fact, are free from such ressure until secured in positionand the va ve therein closed.

This casing headrenders the employment of a threaded cennection'with the well casing o'r tubing unnecessary and avoids bringin the head drm'nward over the tubing and against the pressure therefrom which is most dangerous and costly. The head sections are-applied to the Wei 0 Where the escaping" or oil renders it difiicultor impossible 'pperate and in this manner the head can be ap ied and clamped asing below the point to thecasing by the packet connection without danger of being blown awav by the pressure or otherwise damaged.

1. A casing head formed of segmental sections one of which is provided with a cut ofl' valve and the opposite section with a cooperating seat.

2..A casing head formed of independent sections each provided with abutting flanges, a valve carried by one of said sections, a' seat upon an opposite section to cooperate with said valve, and means for securing said flanges in contact.

3. A casing head formed in ndependent sections each provided with abutting flanges, a valve carried by one of said sections, a seat upon an opposite section to cooperate with said valve, means for securing said flanges in contact, a packing sheet disposed Within said sections, an anchor, and means connectingeach of said sections to said anchor to resist longitudinal movement thereof.

4. A easing head fornred in segmental sections one of which is provided with a lateral connection, means for securing said sections againstlongitudinal movement relative to a well casing, and a valve carried by said lateral connection on one of said sections to control the flow from said casing.

5. A casing head formed in segmental sections, means for securing said sections in contact with each other and with a well casing, a valve carried by one of said sections to control the flow from said casing, an anchor l'or said head, and means for securing said sections to the anchor. v

6. A casing head formed in segmental sections each (provided with flanges .at their abutting e ges, means ior securingsaid flanges together, an anchor, means for securing said sections to said anchor, and a cut oil valve carried by one of said sections.

7. A casing head formed in segmental sect ons each provided with flanges upon their abutting edges, means for securing said flanges in contact with each other, a flange upon the lower end of each section, an anchor, and means for securing said end flanges to the anchor.

A casing headformed in sections adapted to embrace a well casing, packing interposed between said sections and easing, means for securing said sections in engagement with the well casing and with each other, means for securing each section to an anchor, a cut off valve in said casing head, and conducting pipes communicating with each section.

9. A casing head formed in sections to embrace the casing of a well, bolts for secur-- ing sa d sections togct her and n contact with said well casing, means for attaching each section to an anchor, and a cut off valve in said sections.

10. A casing head formed in sections, flanges formed on said sections, securing means passing through said flanges to secure said sections together and in engagement with the well casing, flanges formed on the lower ends of said sections, and securing means passing thercthrough to secure said sections to an anchor.

In testimony whereof, I afiix my signature in presence of two witnesse.
